However, as specifications for Porous Asphalt have traditionally been based empirically on c
28、ompositional recipes combined with specifications for the constituent materials with additional requirements based on performance related tests and as insufficient experience is available with fundamental testing of Porous Asphalt, this European Standard for the moment specifies empirical requiremen
29、ts only. Porous Asphalt is used for surface courses. Porous Asphalt can be laid in more than one layer.

30、 mixtures of the mix group Porous Asphalt for use on roads, airfields and other trafficked areas. NOTE A mixture specification derived from this European Standard can be used either to declare the conformity of a mixture with known requirements or to make known what those requirements are. This Euro
31、pean Standard includes requirements for the selection of the constituent materials. It is designed to be read in conjunction with EN 13108-20 and EN 13108-21. Porous Asphalt mixtures with chemical modified binders not covered by EN 14023 are not covered by this European Standard. 2 Normative referen

The establishment of suitability shall result from one or more of the following: European Standard; European Technical A
47、pproval; specifications for materials based on a demonstrable history of satisfactory use in asphalt. Evidence shall be provided on their suitability. This evidence may be based on research combined with evidence from practice. NOTE In the European asphalt industry it is common practice to use addit
48、ives like inorganic or organic fibres, pigments, waxes etc., which are not covered by a European Standard or ETA. This European Standard allows the use of those materials. 4.2 Binder 4.2.1 General The binder shall be a paving grade bitumen or modified bitumen. The paving grade bitumen shall conform
49、to EN 12591 and the modified bitumen to EN 14023. Natural asphalt conforming to EN 13108-4:2005, Annex B, may be added. 4.2.2 Selection of binder The grade of the bitumen, the type and grade of modified bitumen and the amount and category of natural asphalt shall be as specified. NOTE 1 Given the wide variety of climates, traffic loads, used materials etc. it can be necessary to select on a regional level specific binders.
